According to Landau quantization, the degeneracy of Landau level is approximately $$n=\frac{B}{\Phi_0}$$, where $$\Phi_0$$ is fundamental quantum of flux. My question is, as $$B$$ decreases, why
I think this is counter intuitive, since in classical picture, decreasing $$B$$ makes electrons more like to pass straight thus a more "extended" state.
